To all whom it may concern:

Be it known that I, THOMAS J. KELLY, a citizen of the United States,residing in Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inYarn-Printing Machines, of which the following is a specification.

My invention relates to a machine for printing yarn for warp which isafterward to be woven into tapestry or velvet carpet and the like.

The principal object of my invention is to provide a machine which byslight adjustments may be readily used in printing warp for differentsized rugs or other fabrics.

My invention contemplates means whereby the drum may be readily enlargedor reduced in diameter and in which the other parts of the machine maybe readily adjusted to such changes in size of the drum.

The nature and characteristic features of my invention will be morereadily understood from the following description taken in connectionwith the accompanying drawings forming part hereof in which Figure 1 isa side elevation of a warp printing machine embodying the main featuresof my invention; Fig. 2 is a vertical section thereof taken on the line22 of Fig. 1; Fig. 3 is a perspective view of the outer bearing framefor supporting the drum shaft; Fig. 4: is an enlarged end elevation ofthe drum; Fig. 5 is a fragmentary elevational view of certain portionsof the drum showing the same in detached relationship; and Fig. 6 is anend elevation of one each of the several series of drum segments usedfor forming drums of different diameters.

Referring to the drawings, 7 is the main shaft for supporting the drum,which shaft is mounted in suitable bearings 8 and 9 at the rear and inthe bearing 10 at the front. The bearings 8 and 9 are mounted on asuitable frame work 11 which as hereinafter described may be made sothat the bearings 8 and 9 may be vertically adjusted. The bearing 10 ismounted on a frame work 12 which is likewise provided with means forvertical adjustment of the bearing 10, and the frame work 12 is alsoarranged as to be readily swung away from the front of the drum 13 whenit is desired to remove the printed yarn therefrom. The preferred mannerof so arranging the frame work 12 consists in pivoting the same as at14: near the bottom thereof and providing removable pins or bolts 15some distance above the pivots 14 which look the frame work 12 in itsnormal vertical position. The frame work 12 comprises the verticaluprights 16 suitably braced together, and between the uprights 16 ismounted an adjustable portion 17 which carries the bearing 10 at itsupper portion. The adjustable portion 17 is provided with a series ofopenings 18 which are adapted to register with similar openings in thevertical uprights 16 whereby the adj ustable portion 17 may be raisedand lowered to desired positions and locked at such posi tions by meansof the pins 19 as clearly shown in Fig. 3 of the drawings. The framework 11 is similarly provided with adjustable portions 20 and 21 whichcarry the bearings 8 and 9 to permit the required vertical adjustmentthereof.

Upon the shaft 7 are mounted spiders 22, one at each end of the drum 13,and each arm 23 of said spiders is provided with a series of apertures24 or if desired a slot may be substituted for these apertures. Thespokes 25 are mounted on the spiders 22, one on each arm 23 thereof, andeach spoke 25 is provided with a number of apertures 26 which areadapted to register with the apertures 24 whereby the spokes may beextended by bolting the same through different apertures. Each spoke 25is provided at its outer end with a pair of cars 27 each having a bolthole 28 to permit the segments'29 to be secured thereto by means of theears 30 which are similarly provided with bolt holes 31. The segments 29forming the outer face of the drum 13 are provided in series ofdifferent sizes as shown in Fig. 6 and the circumferential dimensions ofthe several series of segments 29 are correlated to the positions of theapertures 24L of the spider arms 23 and the apertures 26 of the spokes25 so that one series of segments 29 is provided for each possiblelocation of the spokes 25. One of the segments 29 of each of the seriesthereof is pivoted as at 31 (see Fig. 4:) to one of the spokes 25 and tothe other end of the segment 29 is secured a rack 32 which meshes with apinion 33 which is suitably journaled in a specially formed spoke 25 andis mounted upon a shaft 34 which carries a hand wheel 35. By themanipulation of the hand wheel 35, the rack 32 may be retracted to causethe segment 29 to swinginwardly and thus loosen the tension of the yarnupon the drum to allow it to be removed therefrom after the yarn hasbeen printed.

The mechanism for printing the yarn comprises a printing wheel 36 whichis suitably journaled within a box 37 adapted to contain the color. Thebox 37 is mounted in a suitable frame work 40 which is provided withwheels 38 which run upon tracks 39 extending parallel to the axis of thedrum shaft 7 The frame work 40 and the color box 37 are adapted to bereciprocated on the track 39 by means of the rope 41 which passes overpulleys 42 and 43 at the front and rear respectively and is actuated byany suitable mechanism not shown. The arrangement is such that as thecolor box 37 is reciprocated backward and forward on the track 39 theprinting wheel 36 which is partly submerged in the color containedwithin the box 39 will contact with the yarn and print a short length ofeach convolution of the warp which is wound upon the drum l3. v

To rotate the drum to bring the proper portion of the yarn to positionto be printed by the wheel 36 there is provided a pinion 44 mounted upona shaft 45 which shaft also carries a hand wheel 46 for the manualcontrol of the operator. The pinion M meshes with an internal gear 47which is secured in sections one to each of the segments 29 and toinsure the stoppage of the drum at the proper exact location, each ofthe seg ments is also provided with a section of ratchet teeth 48, whichteeth are adapted to be engaged by a pawl 49 which may be looselymounted upon the shaft 45. To enable the foregoing drum actuatingmechanism to be used with all sizes of the drum, the shaft 45 ispreferably mounted in a bearing 50 which may be adjustably secured to anextension 51 of the frame work 21 by means of the bolts 52 and the slot53 in the extension 51.

If desired the means for vertically adjusting the bearings 8, 9 and 10as hereinbefore described, may be dispensed with and in lieu thereof thetracks 39 may be made vertically adjustable by means of the threadedsupporting members 54 as clearly shown in Fig. 1 of the drawings.

Having thus described the nature and characteristic features of myinvention what I claim as new and desire to secure by Letters Patentis 1. In a machine for printing yarn, the combination of a drum adaptedto be altered in diameter, printing mechanism, means for changing thelocation of the printing mechanism with respect to the drum tocompensate for changes in the size of the drum, means for rotating thedrum to bring various parts of the yarn to position to be acted upon bythe printing mechanism, and means for shifting the drum rotatingmechanism to compensate for changes in the size of the drum.

2. In a machine for printing yarn, the combination of the drum, meansfor altering the diameter of said drum, printing mechanism comprising acolor box and printing wheel carried thereby and means for reciprocatingsaid color box, tracks upon which said color box reciprocates, and meansfor raising and lowering said tracks to compensate for changes in thediameter of the drum.

3. In a machine for printing yarn, the combination of the drum, meansfor altering the diameter of said drum, printing mechanism, and meansfor changing the location of the printing mechanism with re spect to thedrum to compensate for changes in the diameter of the drum, the meansfor altering the diameter of the drum comprising extensible spokesmounted on the drum shaft and a plurality of series of various sizedsegments adapted to be interchangeably mounted on the outer ends of thespokes.

4. In a machine for printing yarn, the combination of the drum, meansfor altering the diameter of said drum, printing mechanism, and meansfor changing the location of the printing mechanism with respect to thedrum to compensate for changes in the diameter of the drum, the meansfor altering the diameter of the drum comprising spiders carried by thedrum shaft, spokes extensively secured to said spiders, and a pluralityof series of various sized segments adapted to be interchangeablymounted on the outer ends of the spokes.

In testimony whereof, I have hereunto signed my name in the presence oftwo witnesses.
